I really don't understand this phone craze, why switch the device every few months? I simply don't get this.
Just to answer the question: I've never been an iPhone fan and I highly doubt Apple will surprise us with a physical QWERTY on the 5 - so I'm not interested again. Having said that, I doubt I'll switch to BB10 soon either. My 9900 is good enough for most tasks and unless the Blackberry "N" offers any great improvements for my needs, I won't buy it right away.
